First located by way of malware protection researcher, Leo, facebook (ransomware) is document-encryption malware that behaves further to ransomware-kind viruses. at once after infiltration, facebook encrypts maximum stored statistics and appends filenames with the “.facebook.fb” extension (i.e., “sample.jpg” is renamed to “pattern.jpg.fb.facebook”). Compromised records right away becomes unusable. After a hit encryption, facebook opens a pop-up window.
The main distinction among facebook and ordinary ransomware is that it is not designed to generate sales. The opened pop-up window contains a message (in both Russian and English) claiming that files are encrypted and that encryption/decryption keys have no longer been saved. because of this, restoring statistics is not possible. regrettably, this is accurate. Ransomware builders generate revenue with the aid of encrypting users’ files and promoting (or claiming to sell) decryption keys for masses of even lots of dollars. They provide users with decryption instructions and contact information. fb, however, affords no such facts. The message simply states that documents are encrypted and may by no means be restored. note that the pop-up window’s history carries Mark Zuckerberg’s photograph and a message pointing out that he’s the one answerable for the decryption – “My name is Mark Zuckerberg and i’ve encrypted your files without saving any encryption keys.” this is fake – neither fb nor Zuckerberg have something to do with this malware. fb is probably designed to troll normal users with the aid of definitely “wiping” their computer systems (likely causing giant damage and disruption). alas, there aren’t any tools capable of decrypting information compromised by using facebook. consequently, you can most effective restore the whole lot from a backup.
Although facebook does no longer make ransom demands, it could nonetheless be compared to dozens of different ransomware-kind viruses, including CryptON, RansomAES, GANDCRAB 3, and MMM. those viruses are advanced through special cyber criminals, and but their conduct is equal – all encrypt facts and makes ransom demands. In most instances, ransomware-type viruses have just essential variations: 1) size of ransom, and; 2) kind of encryption algorithm used. regrettably, most employ algorithms (e.g., RSA, AES, etc.) that generate particular decryption keys. therefore, except the malware isn’t always absolutely developed or has sure bugs/flaws (e.g., the key’s tough-coded, stored locally or similar), restoring documents manually without involvement of developers (contacting these people isn’t always recommended) is not possible. Ransomware presents a strong case for keeping normal facts backups, but, it’s far very crucial to keep them on a faraway server (e.g., Cloud) or unplugged garage device (e.g., Flash drive, outside hard drive or comparable), in any other case ransomware encrypts backups as properly.

How to guard yourself from ransomware infections?
The principle motives for pc infections are negative understanding and careless conduct. the key to protection is caution. consequently, pay near interest while browsing the internet. in no way open e mail attachments that seem irrelevant or have been acquired from suspicious/unrecognizable e-mail addresses. these emails must be deleted straight away, with out reading. moreover, download your programs from authentic assets only (using direct download links) and keep away from the usage of 1/3 celebration down load/set up gear, considering that they regularly include rogue applications.
